Use Picture In C# WinForms Or Don't Use?

When I Use Picture (Every Picture) In WinForms in C#.net,My Application is Very Slow.

What Is Solution?

Edit::

I Use Picture From R开发者_开发技巧esource into Background of Form.

It isn't likely that a BackgroundImage slows down your form dramatically. At least on a modern machine. However, it does become a lot more noticeable that your form was slow to begin with. The time taken to render the controls is a lot more visible, especially when the background image is dark. The effect is called "flicker", albeit that it isn't the traditional source of flicker.

My post in this thread shows a few cures for it.
